Abstract: An apparatus and method for receiving a multipath signal in a wireless communication system are provided. The apparatus includes a sample buffer, a buffer index controller, a finger, and a Deskewer buffer and combiner. The sample buffer stores sample data corresponding to a defined number of chips among reception data converted into digital signals. The buffer index controller controls a position of the sample buffer to store the converted data and a position of the sample buffer to output data. The finger receives sample data from a specific position of the sample buffer and demodulates each multipath signal. The Deskewer buffer and combiner eliminates a temporal retard of each demodulated multipath signal and combines the multipath signals.
